KNlFE-SHARPEN ER.

SPECIFICATION formingpart of Letters Patent N 0. 658,417, dated September 25, 1900.

Application filed January 26, 1900- Serial No. 2,861. (No odel.)

To all whom, it may concern.-

Beit known that 1, JOHN H. AGESEN, a citizen of the United States of America, residing and having post-office address at l-Iiggannm, in the county of MiddleseX and State of Connecticut, have invented a certain new and useful Improvement in Knife-Sharpeners, of which the following is a description, reference being had to the accompanying drawings, wherein Figure l is a side elevation view of a knifesharpener embodying said improvement. Fig. 2 is a side or elevation view of the opposite side of said knife-sharpener. Fig. 3 isa top view of the same. Fig. ldenotes an end view or elevation of the knife-sharpener.

The object of the improvement is the production of a knife-sharpener having features of novelty and advantage.

In the accompanying drawings, the letter a denotes the base-plate, and the letter Z) denotes a clamp-plate fixed to and rising from the base-plate.

The letter 0 denotes a removable clampplate, and the letter 61 denotes a screw for attaching the two plates together.

The letteredenotes cutter-pins. Each is attached to one of the clamp-plates, one to each plate, and projects into a mortise in the other clamp-plate.

The letter f denotes circular cutters which are hung on the cutter-pins, and the letterg denotes washers also hung on the cutter-pins and alternating in position thereon with the cutters.

When the device is adjusted for use,the cutters and washers are tightly clamped between the two clamp-plates by means of the screw d.

By loosening that screw the cutters, and for that matter the washers, can be rotated on the cutter-pins, so as to bring fresh parts of the cutters into position for use.

The whole device is intended to be fastened by its base to a table or the like. The edge of a knife-blade is placed down as far as it will go between the two cutters and then drawn through them in the direction indicated by the arrow in Fig. 3.

The device has, or may have, a mode of ad justment not so far described. To that end the mortises b and c, which receive the ends of the cutter-pins, are made oblong, and there is a corresponding oblong mortise c in the removable clamp-blade for the screw. This allows the relation of the two sets of cutters to be so changed relatively to each other as to change their ineetingangle. To aid in this adjustment, the removable clamp-blade is provided with a lip 0 which may be set and fastened into one of the corresponding grooves Adjusting the movable clamp-plate upward brings the clamps nearer together, and vice versa. 7

I claim as my improvement-- In combination, the fixed clamp-plate, the removable clam p-plate, the screw attaching said clamp-plates together, the cutter-pins each attached to a clamp-plate and projectinginto an oblong mortise in the other clampplate, and the cutters hung on said cutterpins; all substantially as described and for the purposes set forth.

JOHN H. AGESEN.
